minor liquid found on U1930. I've replaced and it's still no go. red/green light on the charger but no fan spin.
here's are the measurements:
ppbus_g3h: 8.59v
pp3v42_g3h: 3.42v
rtc: 3.3v
PP5V_S5: 5v
pp3v3_s5: 3.3
pp3v3_s0: 0v -3.3v for a split second then goes 0v. not pulsing.
pp1v5_s0: 0v -1.5v for a split second then goes 0v. not pulsing.
pp5v_s3: 0v -5v for a split second then goes 0v. not pulsing.
pp3v3_sus: 3.3
PP3V3_S4: 0v - gets 3.3v
SMC_ADAPTER_EN: 3.4v
PM_SLP_SUS_L: 3.3v
PM_SLP_S5_L: 0v - 3.3v for a split second then goes 0v. not pulsing.
p3v3s3_en: 0v -gets 3.3v for a split second then goes 0v. not pulsing.
PM_SLP_S4_L: 0v - 3.3v for a split second then goes 0v. not pulsing.
ALL_SYS_PWRGD 0v
pp5v_s4: 0v -5v for a split second then goes 0v. not pulsing.
SMC_BC_ACOK: 3.3v
PP1V05_SUS: 1.05v
cpuvore is 14ohms to ground. A known-good board is around 18-20 ohms.
smc_bypass does quarter fan spin for a couple of times. cpuvcore jumps to 1.1v and pulsing
if I power on without U1930 then all voltages are present, cpuvcore present and stable with fan spin.
I've already tried other bios, it's the same.
